"Scaling Byzantine Fault-Tolerant Systems to Wide Area Networks"

We present the first hierarchical Byzantine tolerant replication architecture suitable to systems that span multiple wide area sites. The architecture confines the effects of any malicious replica to its local site, reduces message complexity of wide area communication, and allows read-only queries to be performed locally within a site for the price of additional hardware. A prototype implementation is evaluated over several network topologies and is compared with a flat Byzantine tolerant approach.
Her work is funded by the Center for Education and Research in Information Security and Assurance (CERIAS), by the Defense Advanced Research Projects Agency (DARPA), and by the National Science Foundation (NSF).
